arm64: dts: qcom: shikra: Add PMIC thermal and ADC support

Add PMIC topic overlay changes for Shikra SOM variants (CQM, CQS, IQS):
- Add pm4125 temp-alarm and VADC channel nodes
- Add pm8005 temp-alarm node
- Add thermal zones for PMIC and system thermistors
- Add GPIO key (volume up) bindings
- Add ADC thermal bridge nodes for pa/quiet/msm thermistors
- Disable pm8005 regulators across SOM variants
- Switch SPMI interrupt to MPM edge-triggered
